I checked the Coolant temp sensor and the harness for voltage and continuity and it checked out good when testing with a voltage multimeter.

I swapped out my Injectors for another set of 370cc and same thing. My injectors and harness
Are reading correctly as tested with a voltage multimeter.


Im very suspicious that it may be my coil packs. Basically when I turn on the motor and I unplug each coilpack from the harness it changes it?s characteristic. However, when I check for voltage it shows a spike of ~ 3.0 + or - and then dips down to 0.00.

I?ve read that coil packs should be showing 5v when testing on a multimeter.
